To calculate the financial independence number (FI number), divide annual expenses by 0.04 (or multiply by 25). For $48,000 annual expenses, the FI number is $1.2 million.
"you take your yearly expenses so if you're spending 4,000 a month which is 48,000 a year you take how much you spend per year and divide it by that 4% rule so 04 remember to move the decimal over two to the left and you get $1.2 million"
